Specification of Letters Patent.

Patented May 9,1922.

Application filed July 31, 1918. Serial No. 247,849.

To (all whom it may concern:

Be it known that we, JOHN V. MoMANrs and FRANK TTOENIGKRAMER, citizensof the United States, residing, respectively, at Kirksville, county of:Adair, State of Missouri, and at Cincinnati, in the county of Hamiltonand State of ()hio, have invented certain new and useful Improvements inTreatment Stools, 01 which the following is a specification.

Our invention relates to improvements in treatment stools. -One of itsobjects is to provide an improved stool to administer osteopathic andsimilar treatments. Another object is to provide improved means tosupport, adjust, and clamp the seat to different positions. Anotherobject is to provide improved means to retain the stool and patient inposition relative to the stool supporting means during the treatments,or to enable the operator to maintain definite relations to the patienton the stool. Another object is to provide'adjustable and detachablemeans to support the back upper portion of a patient relative to eithera rlgid or an adjustable seat. Our invention also comprises certaindetails of form, combination and arrangement, all of which will be fullyset forth in the description of the accompanying drawings in which:

Fig. 1 is a side elevation of a stool embodying our improvements.

Fig. 2 is a section taken on line 2 2 of Fig. 1.

Fig. 3 is a plan of the operators foot rest, detached.

F .41 is a sectional detail of F ig. 1.

Fig. 5 is a bottom plan of one of the clamping members, detached.

on line A: 4;

6 is a perspective view of another clamping member, detached.

Fig. 7 is a view similar to Fig. 1 illustrating a modification. I

Fig. 8 is a plan of the several members of the back support of Fig. 7detached from the stool.

F ig. 9 is a detail illustration of a modified and adjustable backsupport.

The accompanying drawings illustrate the preferred embodiments of ourinvention, in Figs. 1 to =6 of which 7 represents a base havingpreferablya plurality of legs 8 to rest upon the floor, and an uprightsection 9 provided with a vertical polygonal recess or perforation 10.An adjustable standard 11 of polygonal cross section to register withthe perforation 10 serves to adjustably support a seat 12.

In order to firmly clamp the standard 11 relativeto the base againstmovement endwise or rotatably, we provide a yoke or cap 1 1 to seat uponthe upper portion of the base section 9, being held thereto by means ofa pin 15, preferably tapered, which through its middle portion engages apen foration 16 in the base section 9, and at its ends engagesperforations 17 and 18 in the cap or yoke member 14. The member 14- maybe further secured. to section 9 by a screw19 ii desired. I

The upper portion of the member 9 is cut away. or recessed at one sideof the standard 11 to provide space within the cap 141 to receive themovable clamping member OTCjFHV 20, which seats within and is retainedin position by the cap 1 1. The

jaw 20 is provided with clamping faces 21 to engage a plurality of facesof the stand-- ard 11 in such manner as to firmly clamp the standard 11in any desired position to the base member 9. without lost motion orliabilityof vibration or slipping thereof from its adjusted positionwhen subjected to the strain of administering treatment, as seriousinjury might occur therefrom. The cap member 1 has a threaded recess 22into which is threaded a clamping bolt 241 to bear against the rear faceof the jaw 20 to force and lock the jaw into contact with.the standard11. The bolt 24 is preferably provided with a hand wheel or a crank arm25. A sp1ing26 is coiled about the standard 11 between the seat 12 andthe top of the cap 14, and is designed to exert suificient lifting forceupon the seat to substantially counterbalance the weight of the seat andstandard 11 so that when the clamp 20, is released the seat willautomatically rise to near the upper limit of its adjustment and come torest. Thus the lifting power of the spring being coaxial with thestandard base section 9, and in adjusting the seat the operator placesone hand on the seat and releases the clamp with the other,

" ing the patient in retaining his position upon the seat.

The base section 9 is provided with a rear wardly projecting bracket towhich is attached a foot rest member 31 provided with a series of footrests 32 in pairs at different heights above the floor to serve as footrests for the operator in different treatments, and for treatment ofpatients of different dimensions. A metallic mat or standing plate as isrigidly attached to two legs of the base and rests upon the floor inrear of the stool. The plate 34 also under certain circumstances servessubstantially in the same manner members 32 as a rest for the feet ofthe operator.

In the modification Figs. 7, 8 and 9, the parts are as heretoforedescribed, except that the seat 12 instead of being mounted rigidlyrelative to the standard 11 is adjustably mounted relative to a platecar- 'ried rigidly by the standard 11, by means of ears llcarried byopposite sides of the seat at one end, and ears 42 carried by the plate40, which ears ll and42 are hinged together by the axle At the oppositeend of the seat is a partially squared shaft 44 journaled in earscarried by the plate 4E0 and provided with two eccentrics 4st atopposite ends and a hand operating lever 45. A squared section oftheshaft i lbears against a leaf spring -10 carried by the plate40 to holdthe eccentrics in any adjusted position. Eccentric straps 4:6 engagesaid eccentrics and are also hinged at 47 to cars 48 carried by the seat12, whereby the seat may be tilted at its forward edge upwardly or downwardly from the full line position, of Fig. 7. We have also illustrateda detachable and adjustable support for the back or upper portion of apatient, comprising a pad 50, preferably provided with curved ends toengage under the arms of a patient. This pad 50 has a forked shank 51pivotally' connected by a clamping bolt 52 to a link member 58, which isslotted at 54, and adj-ustably connected by clamping bolts 55 and 55 toa link, section 56 which in turn is pivotally connected by a clampingbolt 57 to the forked arms of a shank 58. The shank 58 is detachablyconnected to the plate 40 by in serting it under the yokes or loops 59and 60 and clamping it in place with a setscrew 61.

The bolts 55 and 55 when loosened permit the sections 53 and 56 to slipendwise relative to each other to increase or decrease the distancebetween the centers 52 and 57 to secure different positions for the pad50. Adjustment of the pad 50 upon the centers 52 and 57 and adjustmentof the seat 12 also provide for securing practically any desiredposition of the pad and seat relative to each other. In the modificationFig. 9 we have shown a pad support 62 to be adjustably supported uponthe bolt 52 in place of the pad 50. The member 62 is provided with twopads 63 and 64: which may be adj usted to and from each other to engageand support patients of different dimensions, the curved ends of saidpads 63 and ea being adjustable to fit snugly under the arms of apatient to retain him in the desired position.

A considerable variety of treatments are designed to be employed upondifferent patients varying considerably in dimensions, which treatmentsare provided for by adjustment of the seat and back, and differentpositions of the operator. In some treatments the patient is positionedupon the seat, and may be harnessed thereto, with or without the backsupporting pad, and the oper- I ator stands upon the mat 34 to retainthe stool in position upon the floor, and the patient in definiterelation to the operator,

while the upper portion of the patient is moved by the operator tovarious positions to secure the desired muscular and joint movements.tient is positioned upon the seat and may be harnessed thereto, whilethe operator is seated upon a chair or table orv other object in rear ofthe patient with the feet of the operator upon one or other pair of footrests 32 and the knees of the operator resting against some portion ofthe spine or back .of the patient the hands of the operator beingemployed to grasp the shoulders of the patient to cause such movementsas desired on the part of the patient. By moving the feet of theoperator from one to another of the several foot rests 32, the knees ofthe v operator may be brought to bear upon any desired portion of theback of the patient to serve as a support in securing the desiredmovements. I

The apparatus herein illustrated and described is capable ofconsiderable modification without departing from the principle/of ourinvention.
